Help!

Guys, there was this webtoon/manga that I read a few months back.
It was about a guy who went around killing the gods/demi-gods because he always came across them having seggs where he was resting or something.
The guy also did the deed with a goddess/demi-goddess and later with another woman, who was like a police, and the guy was disguised as a rookie police inorder to keep the woman safe, because he got a prophecy or something that she was gonna die.
I'm having trouble remembering the name of it. Does anyone know??!!
